Specification of Letters Patent.

Patented Aug. 23, 1910.

Application filed May 22, 1908. (Serial No. 434,409.

To all whom it may concern:

Be it known that I, WILLIAM J. BOYER, a citizen of the United States, residing in the city and county of Denver, State of Colorado, have invented a new and useful Improvement in Car- Sheathing, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to certain improvements in car sheathing, and has for its ob.- ject to provide a simple device for sheathing railway cars by the use of tubular steel or other suitable metal shapes, thereby making the car fire proof, noise proof and preventing passengers from being injured by splinters during a collisionor other similar accident, as would be the case in the old style cars with wooden sheathing.

My invention also serves the purpose of a ventilator, the sheathing being tubular or hollow, and is provided with perforations at suitable places for carrying off the foul inside air and admitting the fresh outside air, with the additional advantage .that no rivets are exposed and the car is protected by a double steel wall.

In the accompanying drawings, Figure 1, is an elevation of a sleeping car, with a portion of the body cut away so as to show my invention as applied to the car, both on the exterior and interior. The window sash can also be made of my hollow metal sheathing.

Similar letters of reference indicate corresponding parts in all figures.

Fig. 2, is a perspective View of two pieces of sheathing embodying my invention, being separated so as to show the method of applying (A) is provided with tongues (I) and grooves (G), the'grooves having depressions and holes (C) provided for the purpose of nailing or riveting to the frame of the car Letter (E) represents the interior of the hollow sheathing. which in this instance is surrounded by four solid walls, F, G H, and I but I provide an opening or slit in the apex of tongue (I), the entire length of the sheathing when found advantageous to the nature of the work to be done, as shown in modified Figs. 9 and 10, Sheet #3.

Fig. 3, is a top view of a piece of sheathing embodying, my invention. Letter (J) represents small offsets or rounded corners both on the face and back of the sheathing so as to form a small bead or groove between the pieces as shown in Fig. 4.

Fig. 4, is a top view. of two pieces of sheathing fitted together and embodying my invention. Letter (K) represents the spaces between the pieces formed by the shoulders (J as shown in Fig. 3. Letter (P) represents perforations for ventilation when required. I

Fig. 5, is a top view of sheathing, letters (A) and (B) applied to the floor with a portion of the upper floor broken away so as to show the under floor. The spaces between the sheathing (K) in this Fig. 5 are very small and the shoulders (J) are not made on sheathing intended for the floors, but the sheathing isfitted as tightly as possible so as to make a neat and smooth appearance on the surface. Letter (L) represents the side sill of a car to which the floor sheathing is fastened.

Fig. 6, represents a sectional view of the flooring as applied to cars; letter (L) is the side sill of a car, to which floors are fastened.

Fig. 7 represents an enlarged sectional end View of hollow .steel sheathing with rounded shoulders (J) embodying my invention; while I have shown in all the figures a V shaped tongue and groove, I do not limit myself to this shape but the grooves and tongues may be made any other shape. I consider the V shape preferable, however.

Fig. 8, is a top and end view of a modified form of sheathing embodying my invention. Letter represents a filler or stiffener driven between the walls of the sheathing where found to be necessary, but this is not often used as the shape of the sheathing usually makes it sufficiently strong for all purposes. Concrete or other plastic material may be used for a stiffener or filler.

Sometimes it may be advisable to use a wooden filler conforming to shape of thefied form of sheathing embodying my inven-' Letter (N) represents a longitudinal opening at the apex of tongue. 0 Fig. 11 is a sectional end view of a moditon. Letters (Q) represent dove-tails provided for the purpose of holding the sheathing together when applied,-the dove-tails in the tongues adapted to interlock with the dovetails in the grooves, letter (B).

Fig. 12 is a sectional end view of the same modified forms as shown in Fig. 11, with the exception that thedove-tail in tongue Q) is opened or slotted longitudinally; per letter (N), for the purpose of fastening or fitting the various sections together from the side.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A cellular metallic sheathing consisting of tubular sections, said tubular sections being formed on one side with a projecting tongue and on the opposite side with .a

groove, said tongues being adapted to be inserted laterally in said grooves, and interlocking means formed by a part of the walls of the tongue and grooves to lock together the tongues into the grooves.

2A cellular metallic sheathing consisting of tubular sections, said tubular sections being formed on one side with a projecting tongue and on the opposite side with a groove, the apex of the tongue being split for the purpose described.

3. A cellular metallic sheathing consistin of tubular sections, said tubular sections being formed on one side with a rojecting tongue and on the opposite si e with a groove, and corrugations formed on the side walls of the tongues and grooves to cause the same to interlock when placed together.
